Experimental Investigation of Cement Mixing to Improve Lake Agassiz Clay
Deep mixing method (DMM) is a ground stabilization technique using lime or cement binders. The DMM has gained increasing applications to minimize ground settlements and increase stability to support structures. However, this ground improvement technique has not yet been used extensively in Manitoba. For the effective design of DMM, mixtures of cement, clay, and water that would produce optimal strength and stiffness are generally determined through laboratory tests. A total of 120 unconfined compression tests were conducted at different amounts of cement in the admixtures, water-cement ratio, and curing periods were conducted on Lake Agassiz clay frequently found in Manitoba. The results were compared with those of Champlain clay found in Ontario and Quebéc and Ariake clay in Japan where extensive data are available. This paper discusses the outcome of the comparison. It was found that the improvement effect of Lake Agassiz clay by DMM is an effective means to increase the strength.
